Product Overview

The Schneider Electric BMEH5840KD (Modicon M580 Series) is a premium redundant Hot Standby (HSBY) Ethernet Programmable Automation Controller (ePAC) processor kit designed for large-scale, high-availability industrial processes. Built for mission-critical operations in oil & gas, power generation, water treatment, and infrastructure, this dual-CPU redundant solution ensures zero-downtime control through continuous hardware synchronization.

Operating on an internal 24 V DC backplane bus supply drawing 360 mA, the BMEH5840KD delivers an expanded 64 MB application program memory, advanced cybersecurity capabilities (Achilles Level 2 certified), and rapid program execution speeds up to 40 Kinst/ms. Protected by a conformal-coated IP20 enclosure rated for harsh ambient environments, the unit weighs 0.88 kg (1.94 lbs) with an estimated gross package shipping weight of 1.55 kg (3.42 lbs).

Core Technical Advantages

  • Expanded 64 MB Application Memory: Features four times the memory capacity of standard M580 processors, enabling execution of complex control algorithms and extensive data logging.
  • Bumpless Hot Standby Redundancy: Dedicated high-speed fiber-optic HSBY synchronization ports provide sub-millisecond data mirroring and instantaneous primary-to-standby failover.
  • High-Capacity Network Scanner: Supports up to 31 Ethernet Remote I/O (RIO) drops and up to 64 Distributed Equipment (DIO) devices directly on the Ethernet backplane network.
  • Severe Environment Protection: Conformal coating (Class 3C4 / Class 3S4 compliant) guards internal electronics against corrosive airborne contaminants, humidity, and dust exposure.

Installation & Setup Recommendations

  • Dual-Rack Redundancy Architecture: Mount primary and standby BMEH5840KD CPUs into identical Modicon X80 Ethernet backplanes connected to independent uninterruptible power supplies (UPS).
  • Fiber-Optic HSBY Link: Interconnect the dedicated optical sync ports on both CPUs using approved multimode fiber cables to ensure uninterrupted memory replication.
  • Software Configuration: Configure project hardware and Ethernet RIO networks within EcoStruxure Control Expert, verifying both CPUs execute identical firmware versions before commissioning.
